The Football Association has charged Ashley Cole's agent Jonathan Barnett with a breach of rules.
Barnett has been charged after Cole's meeting with Chelsea
The charge relates to Barnett allegedly attending a meeting involving Arsenal star Cole, 25, and Chelsea officials at a London hotel on 27 January 2005.
The Premier League has already punished Cole, Chelsea and boss Jose Mourinho.
The charge alleges Barnett brought about a breach of Premier League rules by Cole relating to "illegal approaches to clubs by players under contract."
Barnett has also been charged with a breach of the Fifa Players' Agents Code of Conduct, which require agents to respect the rights of third parties - in this case Arsenal.
He has until 20 April to respond to the charge.
Cole was fined £75,000 by the Premier League - while Chelsea boss Mourinho also was fined £75,000 in the dispute and the club £300,000 by the Premier League in August, of which neither appealed.
The Premier League had no powers to punish Barnett in the so-called "tapping up" affair.
